Galaxy Nexus & Android Face Unlock - Facial Recognition

The Galaxy Nexus has a neat little feature which will be first available on the device. It is "Face Unlock". The feature lets you unlock your Ice Cream Sandwich device with your face, no need to put in any numbers or swipe on the screen. Just look into the camera and the phone will do the rest. It can be great for security purposes and puts off anyone unauthorised trying to get into your device.
